A melt-blowing die tip includes a first die tip half and a second die tip half with complementary mating surfaces. A flow system is engraved onto at least one of the mating surfaces. The flow system includes linear melt troughs, which are fluidly connected by channels. Spinning orifices downstream of the last melt trough, which may have diameters over an exceptionally broad range, produce fibers as small as nano-scale. Fasteners secure the two die tip halves, and at least one of the channels includes a curved portion to direct flow around a fastener. The resulting die tip has increased pressure tolerance, greater productivity, reduced costs, and supports the economical mass production of super fine fibers. Optionally, an engraved die plate may be inserted between the die tip halves. When both sides of the die plate are engraved with a flow system, the die may produce bi-component fibers.
